RAIL-FASTENING.

Specification of Letters Patent.

Application led July 23, 1910.

Patented Apr. 25, 1911.

Serial No. 573,576.

T 0 all whom tt may concern:

Be it known that I, CIL/xmlns B. SILK, a citizen of the United States of America, and resident of Massillon, county of Stark, and State of Ohio, have invented certain new and useful Improvements in Rail- Fastenings, of which the following is a specification.

This invention relates to improvements in rail-fastenings, and more particularly to means for fastening railway-rails in place; and it consists in the particular construction, arrangement and combination of parts which will hereinafter be fully described.

The primary object of the invention is to provide simple and inexpensive means whereby railway rails may be securely fastened in place upon metallic or similar crossties.

A further object is to provide a fastening means of -the character mentioned which may be readily adjusted from time to time to compensate for any wear which may occur.

In describing the invention in detail, reference is herein had to the accompanying drawing, forming a part of this specification, in which- Figure l is a top plan view of a cross-tie, showing rails secured thereto by means of my said invention; Fig. 2 is an enlarged top plan view of the adjustable rail-chair sections, the same being shown in rail-ren ceiving position; Fig. 3 is a similar view showing said sections in rail-gripping position; Fig. 4 is a longitudinal section on thev line IJs-4, Fig. 2, showing a rail seated on the chair sections; Fig. 5 is a similar section on the line 5 5, Fig. 3, showing a rail seated on the chair sections; Fig. 6 is a horizontal section on the line 6-6, Fig. 4; and 1Fig. 7 is a detail perspective view of the Referring to said drawing, in which like designating characters distinguish like parts throughout the several views-1 indicates a cross-tie which may be made 'of metal. concrete, or other appropriate material, being preferably of a hollow rectangular type, as shown. Provided in the upper face of said tie and extending diagonally across the median line of the rail to be mounted thereon and at a predetermined distance apart are two parallel slots '2, each of which terminates at one end, said ends being opposite in the two slots, in an enlarged aperture 3. The head 4t of a downwardly-extending stud 5 is projected through each aperture 3, said apertures being of a size which will just admit of the passage therethrough of said heads. Each of said studs is carried by the under side of the flat body portion ofia chair-section 6 adapted for having a rail 7 mounted thereon.

Each of the chair sections 6 terminates at one end in an upwardly and inwardly inclined hook or clamp 8 adapted for gripping engagement with the base of a rail 7. Said chair sections are mounted upon the tie in oppositely disposed relation and have their adjacent edges inclined so as to preferably lie in parallel alinement, and so as to coincide when they occupy extended positions, as shown in Fig. 2. For the purpose of renden ingl said sect-ions interchangeable, the opposite edges of each are both inclined toward the end which bears the hook S, giving said section a tapered form. Wien said sections 6 occupy positions in extended relation, as shown in Figs. 2 and 4,-that is, in the positions in which they are initially mounted upon the tie l-the hooks 8 are separated a distance which adords ready access of a rail 7 to a seating position. When the rail has been seated. as shown in Fig. 4, the chair sections are each driven inward, Acausing the studs 5 carried thereby to move forward along their respective slots 2 until the hooks 8 assume clamping engagement with the o pposite sides of the rail base. as shown in Figs. 3 and 5. In so moving along said slots, the chair sections are forced apart, leaving an open space between the adjacent edges thereof. Then, for the purpose of securely maintaining said chair-sections in their adjusted positions, a slightly tapered wedge or key 10 is driven into said open space, as shown in Figs. 3 and 5. A horizontally disposed kerf 9 is preferably provided in the tapered or smaller end `of said key, as is clearly shown in Fig. 7. When the key has been driven into place, the upper tongue 11 is turned back into clamping engagement with the rail base.

As is apparent, when it is desired to readjust the parts composing the fastening hereinbefore described, as for compensating for wear taken place, the chair sections may be driven up into closer engagement with the rail-base, the key driven forward, and the tongue ll bent into close engagement with said rail base.

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is

l. The combination with a cross-tie of a hollow type having a pair of diagonally dirented slots inits top adjacent to each end thereof, of a headed stud movable in each of.

said slots, a rail-chair section in fixed relavtionto each studeach of said sections having a terminal hoolradapted for engaging'a rail base, and means for maintaining said sections in adjustedrail clamping position.

The combination with a cross-tie of a hollow type having a pair of diagonally directed slotsin its top adjacent to each end thereof, of aheaded stud movable in each of said slots, a rail-chair section in fixed `rela.- tion to. each stud, said .sections havingl their adjacentl edges inclined and lying in substantially parallel alinelnent, a terminal hookformed on each ofsaid sections, said hooks being disposed in opposing relation, -andmeans for maintaining said sections 1n adjusted clamping engagement with a railway-rail mounted thereon. i h

3.
